It would be great if an option was added to watermark the image before the thumbnail was generated, that way the watermark gets scaled along with the image. Since the plugin doesn't do this now, the watermark ends up obscuring large portions of the image. It would be nice to have a configurable option to add WM before or after thumbnail generation so those that like a disproportionate WM (as it is now) can retain that behavior, but those that wish the WM to be scaled with the rest of the image could enable it.
